Biology of bats!

The video discusses three NSF-funded research projects. The first project, led by Texas A&M University and the University of Colorado, explores alternative bridge structures to withstand earthquakes, focusing on hybrid sliding rocking columns. The second project, by Vanderbilt University, investigates cancer cell migration, revealing that cells prefer paths of least resistance to conserve energy, which could inform new metastasis prevention strategies. The third project, conducted by Brown University, examines temperature variations in bat wings during flight, offering insights into muscle adaptation in extreme temperatures, with potential applications for humans working in harsh conditions.

What is the main advantage of the hybrid sliding rocking (HSR) columns over traditional bridge columns during an earthquake?

• They allow for aesthetic designs.

• They are easier to maintain.

• They are cheaper to construct.

• They can shift and rock without damage.

Why do cancer cells prefer wider spaces for movement?

• To avoid other cells.

• To increase their speed of migration.

• To conserve energy during movement.

• To avoid detection by the immune system.

What did researchers at Brown University discover about bat wings?

• They do not change temperature.

• They are always at body temperature.

• They operate at a lower temperature than the body.

• They are warmer than the rest of the body.

How does the temperature of bat wing muscles change as you move from the shoulder to the hand?

• It remains constant.

• It increases gradually.

• It decreases significantly.

• It fluctuates randomly.

What potential human application could arise from understanding bat muscle adaptation?

• Improving human exercise regulation in extreme temperatures.

• Enhancing human muscle strength.

• Developing new flight technologies.

• Creating better thermal clothing.
